BIRDS OF BRITISH BURMAH. 
rump and upper tail-coverts dull black ; tail brown ; wing-coverts and 
quills brown tinged with green ; the first primary with a good deal of white 
on the inner web^ the others progressively with more, till the fifth becomes 
nearly all white with a black tip, after which the white again decreases in 
extent; secondaries white, with a broad black tip, the white forming a 
conspicuous wing-spot ; tertiaries glossed with green. 
The female differs from the male in having the head and neck more or 
less brown, the feathers edged with reddish ; and the upper plumage is 
brown, instead of brownish black or dull black ; the other parts of the 
plumage are the same as in the male. 
Bill plumbeous ; iris white ; legs and toes plumbeous ; claws blackish. 
Length 16 inches, tail 3, wing 7' 5, tarsus 1-2, bill from gape 2. The 
female is of about the same size. 
The White-eyed Pochard occurs, according to Mr. Blyth, in Arrakan. 
There is no record of its occurrence elsewhere in the Province. 
It occurs throughout the southern half of Asia, the greater part of 
Europe and Northern Africa. Its south-eastern limit, so far as is at pre- 
sent known, is Burmah and China. 
This little Duck, although probably rare in Arrakan, is very common in 
many parts of India as a winter visitor, arriving in October. It frequents 
weedy swamps and ponds. It breeds immediately north of India, making 
a nest of grass in reeds on the edges of lakes, and laying some ten very 
pale buff eggs.
